ROLLING METAL BARS.

. SPECIFICATION forming part of Letters Patent No. 302,295, dated July22, 1884.

Application filed January.14, 1884.

To aZZ whom it may concern: Be it known that I, WILLIAM A. SWEET, ofSyracuse, Onondaga county, State of New York, have invented a new anduseful Improvement in Apparatus Used in Rollin g Metal Rods, by'whichthe danger in running the bars or rods from the rolls over the floor isavoided, the rods being kept straight, their heat more completelyretained, and the usual oxidation partly prevented in the process ofrolling. I attain these objects by the device illustrated in theaccompanying drawings, in which Figure 1 is a vertical section throughthe receiver. Fig. 2 is a plan of the same.

The letters of reference are the same for like parts in both figures.The construction and application of my new device are as follows: Oneach side of a train of rollers I place a receiverconsisting ofastraight tube of metal, a, having a flaring mouth, Z which curvesupward and opens opposite the rollers, so that when the rod is projectedfrom the rollers it enters said mouth b and runs down into the tube a,which is buried beneath the fioor, as shown by the dotted lines o 0,surrounded by any suitable non-conductor of heat.

This device prevents the rod from coming into contact with the workmen,keeps it clean, re-

tains in greater measure itsheat, and holds it straight. I prefer toplace in this receiver a (No model.)

quantity of carbonaceous material, into which the rod is thrust, andigniting it fills the tube with smoke or carbon vapor, forming anatmosphere that envelops the heated rod. When in operation, the rod runsfrom the rollers into the mouth of the receiver until its rear endleaves them. It is then seized by the operator and. returned in theusual way to the rolls and passes through in the opposite direction,en-' tering the receiver on the opposite side, and

so on till the rod is reduced sufficiently for the purpose intended.

By this device all danger is avoided of the operator being struck by therod rapidly projected from the rolls. The rod is kept clean,
